The Siegfried is an example of a Knight Giga Fortress.
A Knight Giga Fortress is a derivation of the Knightmare Frame, characterized by its lack of limbs, immense size, and durability. Such fortresses are essentially hovering assault craft, using a Float System to maneuver themselves through the air, and can be equipped with multiple Slash Harkens, Hadron Cannons, and other weapons.
